Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"coarse learning predation algorithm" » "coarse learning predators algorithm", "coarse learning estimation algorithm", "coarse learning prediction algorithm", "coarse learning emotion algorithm", "coarse graining predation algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("coarse learning predation algorithm") or ("modified multiobjective optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("coarse learning predation algorithm") OR ("modified multiobjective optimized algorithm")).
• Removing quotes may allow a broader search: (( coarse learning predation algorithm ) or ( modified multiobjective optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("coarse learning predation algorithm") or ("modified multiobjective optimized algorithm"))*.
